Abstract 12880: Malnutrition Assessed by Geriatric Nutritional Risk Index Provides the Long-term Prognostic Information in Patients Admitted for Acute Decompensated Heart Failure, Regardless of Reduced or Preserved Left Ventricular Ejection Fraction; A Comparison With Prognostic Nutritional Index and CONUT Score

Abstract

Backgrounds: Malnutrition is associated with increased mortality risk in patients (pts) with acute decompensated heart failure(ADHF). Nutritional status is assessed by several indices, such as Geriatric Nutritional Risk Index (GNRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) score. However, there is no information available on the comparison of prognostic significance of these indices in ADHF pts, relating to reduced or preserved left ventricular ejection fraction (HFrEF or HFpEF). Methods and Results: We studied 303 consecutive pts admitted for ADHF and discharged alive (HFrEF(LVEF<50%);n=163, HFpEF(LVEF≥50%);n=140). Nutritional status was evaluated at the discharge by GNRI calculated as follows: 14.89 • serum albumin (g/dl) + 41.7 • BMI/22, PNI calculated as follows: 10 • serum albumin (g/dl) + 0.005 • total lymphocyte count (/ml) and CONUT score calculated by serum albumin, total cholesterol levels and lymphocyte count. During a follow-up period of 5.0±4.3 yrs, 75 pts had cardiovascular death (CVD). At multivariate Cox analysis, GNRI (p<0.0001) was significantly associated with CVD, independently of systolic blood pressure, serum sodium level and eGFR, although PNI and CONUT score showed a significant association with CVD at univariate analysis. ROC analysis revealed that GNRI of 88 was a fair discriminator for CVD (AUC 0.70(95%CI 0.63-0.77), p<0.0001). In group with HFrEF, CVD was significantly more frequently observed in pts with than without low GNRI <88 (48% vs 25%, p<0.0001, adjusted HR 3.5[1.8-6.6]). Furthermore, in group with HFpEF, pts with low GNRI had the significantly increased risk, compared to those with high GNRI>88 (36% vs 10%, p<0.0001, adjusted HR 3.8[1.4-10.2]). Conclusion: Malnutrition assessed by Geriatric Nutritional Index provides more valuable long-term prognostic information than PNI and CONUT score in pts admitted for ADHF, regardless of HFrEF or HFpEF.
